ROLLER-ZBEARING.

To all whom it'may concern:

I Bev it known that I, CHARLES O. JOHNSON, a citizen v of the UnitedStates, residing in Boston, countyrof Suffolk, and lState oiMassachusetts, h'ave invented an Irn'prove-rmntV in Ro 1l'er-Bearin`gs`, of which the o1low ing description, connection with theaccompanying drawing -llhis inventionlias for its object theproduction'of a novel, serviceable, and durable bearing of theroller-and The`novel` bearing shown' as embodying my inventioncomprisesa rigid cage provided with a series oi bearing rollers cupped attheirends to receive balls v: -1 .ssaid rollers, the .end walls oi thecage opposite thel ends that are sustained in the line othe'longitudinal axes of of said rollers being provided with through andthrough ff holes or openings of slightlv less diaineter than the di`Aarneter of the single ba serve to resist end thrust, and to maintainthese bearing rolls in their correct operative relation, and with theirI longitudinal'axes in. parallelism with the longitudinal axis of theshaft, I have combined with said bearing rollers av series oi guiding'rollers that Contact with the exteriors oi the bearing'rollersand'movlng therewith also act to space 4the bearing rollers, aiding iniurtherpreserving theirparallelism.

'Figure 1 shows in section a box and housing surrounding an axle thelatter being shownin elevation, the upper "part oi theroller carryingcage being broken out showing one oi the' bearing rollers in section;Fig. 2 is 'a section in the line at, Fig. l, with the balls inelevation; Fig. 3 is la partial section -in the line sc, Fig. l and Fig.4 is-a section through the cage in line with one ol its vties andtherollersustaincd thereby. Fig. 5 is an venT larged detail showing thepart oi the cage end with a ball-receiving space therein. i

These guide rollers maybe supported by the rings 'e oi thecage in any suitable way and in the present aiihbodirnent oi myinvention-they are loosely mounted specification of Letters Patent.'Application nedrovembr '16,1906.

Ateach end oi the cage 1 have interposed between the walls v2, 3,-oi thehousing antifrictionV `washers h, h, againstwhich thel balls v11 bear asthe'shait or box and its housing are rotated. The object ol' thesewashers is to take the wear but they could be ornitted and the ballsallowed to bear directly againstthe housing C withoutileparting from theinvention.

When assembling the cage, itv willbe understood that the balls andbearing rollers are positioned in the' cage before the tierods c areupset, and aiter upset' ting these rods to connect/*the-endrings oftheycage rigidly, the bearing rollersand balls canneI dropout.

The'cage connected by the tie-rods and provided with -the bearingrollers sustained at each end by a single ball vb is slipped'over theaxle and within thebox B surrounded by the housing. The cage may be heldinthe housing by any proper means such as the lace plate Cf, which isshown as removably connceted'to the body oi thel housing by screws .C"'.The space within the housing occupied by the cage is just sumcientl topermit a slight motion endwise thereof and its balls b between the endbearing surfaces.
